Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed June 20, 1906- Serial No. 322,5d1.

To all whom it may concern:

Be it known that 1, JOHN GROSSGEBAUER, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of NewJersey, have invented a new and Improved W indow-(Jleaner, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a device especially adapted for cleaning the vestibule windows of trolley or motor cars, or the windows of engine cabs or other vehicles from frost, rain, snow or hail, or excessive dust deposited thereon during a storm, which device is a lixture and is operated from within the vehicle by the motorman, or an engineer, thus enabling such persons to maintain a clear look-out even in the face of a severe storm.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of a portion of a motor car and the improved device applied; Fig. 2 is an enlarged vertical section through the improved cleaning device and its support, the section being taken substantially on the line 22 of Fig. 3; and Fig. 3 is a horizontal section taken substantially on the line 3--3 of Fig. 2.

A represents the vestibule of a trolley car of that type which is provided with. a central window A and side windows A The improved cleaning device is shown applied to the central window and is located at the exterior thereof, but it will be understood that the device may also be applied to the two side windows, or to any other window oi a car or vehicle where it is desirable to use it.

Where the device is to be applied, one side rail 10 of the window sash is provided witlrliorizontal openings 11 located adjacent to the top and the bottom of the said side rail, as is shown in Fig. 2. A substantially U-shaped bracket 12 is usually employed in connection with each opening 11, being introduced therein from the outside, the bow sections 13 of said brackets ex tending beyond the outer face oi the said side rail; and to the outer or bow sections 1.3 01 the brackets 12 a guide rod or bar 14 is secured, and said guide rod or bar 14 is secured at its ends to the side rail 10 of the window frame by bolts 1.5 or their equivalents, and is spaced lrom the said side rail by plugs 15*, as is also shown in Fig. 2. Guide rollers 16 are mounted to turn in the brackets 12, and an endless belt 17 is passed over the guide rollers 16, which belt extends down along the inner and outer faces of the window sash rail 10 as is also shown in Fig. 2. The belt 17 at its inner stretch is provided with an attached button 17, a handle or the like, whereby the belt may be made to move 18 is provided with an attached loop or sleeve 19 at its back, through which the bar 14 passes, and this loop or sleeve 19 is secured to the belt by means of a rivet 20 or its equivalent. The cylinder 18 is closed at the bottom and is substantially open at the top, and contains a coiled spring 21, held in place by lips 22 formed at the top oi the cylinder; and the lower end 23 of the spring 21 is carried down through the bottom of said cylinder. The upper end of the spring 21 is carried horizontally across the outside of the window which is to be cleaned by the device, forming thereby a horizontal support 24 for a clamp 25, which clamp carries a strip of rubber 26, or a strip of cleaning material adapted to be held in constant engagement with the window pane by the pressure of its spring support 24 induced by the coil 21. Thus it will be observed that the cleaning material 26 being always against the window pane, by moving the handle 17 or its equivalent up or down, the cleaning arm is made to move up or down the window pane and will thus clean thereirom weather marks, or any rain, accumulated snow, dust or the like, enabling the person within the vehicle to conveniently and speedily clear a window from material accumulated thereon and which might obstruct the view. 2

I desire it to be understood that other means may be employed than those shown for operating the endless belt; or the cleaning arm may be moved up or down in engagement with the glass by means equivalent to those shown without departing from the spirit ol the invention.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:-

1. in a window cleaner, a vertically arranged guide bar, a coiled spring, supporting means for the spring, a clean ing arm extending from one end of said spring, a sleeve connected with the supporting means for the spring and mounted to slide on said guide bar, an endless carrier se cured to the sleeve, and guides [or the carrier.

2. In a window cleaner, a guide bar, a cylinder provided with a sleeve mounted to slide on said guide bar, a coiled spring held in said cylinder, a cleaning arm extending from one end of said spring, the said arm being exterior-1y lo- 'cated and normally held in engagement with a window pane by the said spring, and means connected with the sleeve for carrying said arm upward and downward in engagement with said window pane.

The combination with the side rail of a sash, of a window cleaner comprising an endless belt passing through the said guide rail and extending at the inner and outer faces thereof, guides for the said belt, a guide bar secured to the side rail, a coiled spring, a cylinder in which said spring is held, a sleeve connected with said cylinder and mounted to slide on said guide bar, the said sleeve being secured to the outer stretch oi said belt, and a cleaning arm extending from one end oi. said coiled spring.

The combination with a side rail of a window sash having upper and lower o1'1enings therein, and guide rollers in said openings, of an endless belt passed through said openings and over the guide rollers, the longitudinal stretches of the belt being at the inner and outer faces of -the rail, a guide rod secured to the outer face 01 the rail,

:1, sleeve through Which the guide rod passes, a cylinder connected with the said sleeve, a coiled spring held in said cylinder and having one end extending horizontally across the window and forming a cleaning arm, and means for attaching the said sleeve to the belt 111 a Window cleaner, a vertically arranged guide bar, a cylinder closed at its bottom and provided at its back with a sleeve mounted to slide on said guide bar, a coiled spring held in said cylinder, the upper end of said spring extending horizontally across the outside of the window and forming a cleaning arm, cleaning material carried y said arm and normally held in engagement with a window pane by the tension oi? the coiled spring, and means i-onnected with the said sleeve for movnig said a1'1n upward and do W11 '11 rd.

(3. in a window cleaner, :1 spring, a holder for the same. means [or moving said holder vertically, and means for guiding said holder, the said spring having a cleaning :11'111 extending from one end thereof across the window.

I11 testimony whereof-l have signed my name specification in the presence of two subscribing \vilnossos.
